A couple of Permian echinoderms from Indonesia

I was at home of a fossil dealer not to long ago when he brought out some echinoderms that he'd picked up at the Tuscon show. They were from Indonesia, more specifically the island of Timor and are Permian in age.

The first one is Timorocrinus mirabilis which I think is a type crinoid but it's hard to find any information online.It looks very similar to a blastoid but I can't see any ambulacra (mesh like openings) in the gaps between ridges as one would expect.

These next two specimens are true blastoids called Deltoblastus

The label that was included with all three specimens stated that the fossils came from the Maubisse formation near Basleo on the island of Timor.
